BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates generally to a die for manufacturing shimsand, more particularly, to a die having a plurality of divisions throughwhich a source material plate is repeatedly moved and pressed intovarious types of shims, which are in turn automatically sorted andcollected by the types without being mixed, thereby manufacturing agreat quantity of shims using the source material plate with minimalloss of materials.

Description of the Related Art

Generally, in a conventional process of manufacturing shims, a sourcematerial plate should be cut into at least 50 shims. Here, if the 50shims are cut simultaneously in a die, a problem arises in that the dieis damaged due to the limit of rigidity thereof.

Further, in the case of using a cutting method, rather than a dieforming method, after a source material plate is marked with shim formsto be cut, the marked shim forms are cut into shims with a complexcutting process using e.g. metal-cutting scissors, wire-cutting,saw-cutting, etc.

However, the conventional process has problems in that in the course ofmanufacturing the shims, loss of materials occurs, and the sourcematerial plate is curved so that the shape of the shim is deformed todegrade the quality of the shim.

Therefore, it is currently required to provide a technique ofmanufacturing a great quantity of shims in a short period of time withminimal loss of a source material.

The foregoing is intended merely to aid in the understanding of thebackground of the present invention, and is not intended to mean thatthe present invention falls within the purview of the related art thatis already known to those skilled in the art.

DETAILED DESCRIPTION OF THE INVENTION

Hereinbelow, preferred embodiments of the present invention will bedescribed in detail with reference to the accompanying drawings.However, the embodiments are merely provided for easy understanding ofthe invention, so the present invention is not limited thereto.

FIG. 1 is a view illustrating a configuration of a die 100 formanufacturing shims according to an embodiment of the present invention.

Referring to FIG. 1, the die 100 may generally include a lower die block110, an upper die block 120, and a collecting box 130.

The lower die block 110 may serve as a place on which a source materialplate for a shim is seated and located, with a plurality of diedivisions formed on an upper surface thereof.

Specifically, the lower die block 110 may be divided into first tofourth die units 111, 112, 113, 114 adjacent to first to fourth sidesthereof (not shown).

Here, the first to fourth die units 111, 112, 113, 114 may be coupled toan upper surface of the lower die block 110 by means of one or morebolts. Thus, the first and fourth die units 111, 112, 113, 114 may berespectively decoupled from the lower die block 110. The first to fourthdie units 111, 112, 113, 114 may have different shapes, so the die unitsmay be replaced with new die units or other die units having differentshapes.

The first die unit 111 may be a die unit which is provided on the upwardleft side on the lower die block 110, the second die unit 112 may be adie unit which is provided on the upward right side on the lower dieblock 110, the third die unit 113 may be a die unit which is provided onthe downward right side on the lower die block 110, and the fourth dieunit 114 may be a die unit which is provided on the downward left sideon the lower die block 110. The reason why the first to fourth die units111, 112, 113, 114 are divided is because a source material plate 1 issequentially moved from the first to the fourth die units 111, 112, 113,114. Then, the source material plate 1 is first pressed for an emptyspace by the first die unit 111 and moved to the second die unit. Then,the source material plate 1 is first pressed for an empty space by thefirst die unit 111 and moved to the second die unit 112. Then, thesource material plate 1 is secondarily pressed for an empty space by thesecond die unit 112 and moved to the third die unit 113. Then, thesource material plate 1 is thirdly pressed for an empty space by thethird die unit 113 and moved to the fourth die unit 114. Finally, thesource material plate 1 is fourthly pressed for an empty space by thefourth die unit 114.

With the multiple pressing stages, a plurality of shims 1 a may bemanufactured from the source material plate 1.

Here, since the first die unit 111 may have about 15 shim-shaped formingparts, the first pressing stage may produce 15 shims 1 a.

Further, since the second die unit 112 may have about 10 shim-shapedforming parts, the second pressing stage may produce 10 shims 1 a.

Further, since the third die unit 113 may have about 15 shim-shapedforming parts, the third pressing stage may produce 15 shims 1 a.

Finally, since the fourth die unit 114 may have about 10 shim-shapedforming parts, the fourth pressing stage may produce 10 shims 1 a.

That is, consequently, while the source material plate 1 is moved fromthe first die unit 111 to the fourth die unit 114, at least 50 shims 1 amay be produced from the source material plate through four pressingstages, and the 50 shims 1 a are downwardly discharged toward thecollecting box 130.

Collecting channels (not shown) may be provided between the first tofourth die units 111, 112, 113, 114 and the collecting box 130 to allowthe shims 1 a to be discharged therethrough.

In the meantime, although FIG. 1 illustrates that the lower die block110 is divided into four sections, i.e. the first to fourth die units111, 112, 113, 114, the first die unit 111 may mean a combination oftotal 15 forming parts which are bolted to the lower die block 110, thesecond die unit 112 may mean a combination of total 10 forming partswhich are bolted to the lower die block 110, the third die unit 113 maymean a combination of total 15 forming parts which are bolted to thelower die block 110, and the fourth die unit 114 may mean a combinationof total 15 forming parts which are bolted to the lower die block 110.

That is, while FIG. 1 illustrates four die units, the four die units mayinclude 50 forming parts which are respectively bolted to the lower dieblock 110 to suit respective shapes of shims.

Next, the upper die block 120 is located opposite the upper surface ofthe lower die block 110, wherein a lower surface thereof may correspondto the upper surface of the lower die block 110, i.e. the first tofourth die units 111, 112, 113, 114. The upper die block 120 may beprovided so as to be vertically movable downwards from the upper side ofthe lower die block 110, so that the upper die block serves todownwardly press the source material plate seated and located on thefirst to fourth die units 111, 112, 113, 114.

The upper die block 120 may be divided into fifth to eighth die units121, 122, 123, 124 adjacent to fifth to eighth sides thereof (notshown), opposite the first to fourth die units 111, 112, 113, 114.

Here, the fifth to eighth die units 121, 122, 123, 124 may be coupled tothe upper die block 120 by means of a plurality of bolts, so the fifthto eighth die units may be respectively separated from the lower side ofthe upper die block 120.

When coming into contact with each other, the first to fourth die units111, 112, 113, 114 and the fifth to eighth die units 121, 122, 123, 124may have the same contact surface.

Since the first to fourth die units 111, 112, 113, 114 and the fifth toeighth die units 121, 122, 123, 124 have the same function except fortheir locations, a detailed description thereof will be omitted. Likethe first to fourth die units 111, 112, 113, 114, the fifth to eighthdie units 121, 122, 123, 124 are bolted to the upper die block in orderto be replaced with new die units or other die units having differentshapes, if needed.

In an embodiment, the first to fourth die units 111, 112, 113, 114 maybe provided on the respective sides thereof with one or more protrusions115 to prevent the source material plate 1 from turning off the first tofourth die units 111, 112, 113, 114.

Thus, while the source material plate 1 is moved from the first die unit111 to the fourth die unit 114, the source material plate is preventedfrom turning off the first to fourth die units 111, 112, 113, 114 by theprotrusions 115.

In the meantime, although FIG. 1 illustrates that the upper die block120 is divided into four sections, i.e. the fifth to eighth die units121, 122, 123, 124, the fifth die unit 121 may mean a combination oftotal 15 forming parts which are bolted to the upper die block 210, thesixth die unit 122 may mean a combination of total 10 forming partswhich are bolted to the upper die block 120, the seventh die unit 123may mean a combination of total 15 forming parts which are bolted to theupper die block 120, and the eighth die unit 124 may mean a combinationof total 15 forming parts which are bolted to the upper die block 120.That is, while FIG. 1 illustrates four die units, the four die units mayinclude 50 forming parts which are respectively bolted to the upper dieblock 110 to suit respective shapes of shims.

Next, the collecting box 130 is located below the lower die block 110 soas to collect the shims 1 a through collecting channels (not shown)provided below the first to fourth die units 111, 112, 113, 114 of thelower die block 110. This is illustrated in detail in FIGS. 2 and 3.

FIG. 2 is a detailed view illustrating a collecting box 130 of the dieillustrated in FIG. 1, and FIG. 3 is a view illustrating shims 1 a beingsorted and collected by partition walls 131 a, 132 a of the collectingbox 130 illustrated in FIG. 2.

Referring to FIG. 2, the collecting box 130 may include a firstcollecting box section 131 provided below the first and fourth die units111, 114, and a second collecting section 132 provided below the secondand third die units 112, 113.

The first and second collecting box sections 131, 132 may be able toslide outwards or inwards from the lower die block 110.

Thus, when the first and second collecting box sections 131, 132 arefully collected with the shims 1 a, the first and second collecting boxsections 131, 132 are drawn from the lower die block 110 so that theshims collected therein can be obtained.

Referring to FIG. 3, the first and second collecting box sections 131,132 may be respectively provided with the partition walls 131 a, 132 a,through which the shims 1 a are collected from the first to fourth dieunits 111, 112, 113, 114.

The partition walls 131 a, 132 a may be configured such that internalspaces of the first and second collecting box sections 131, 132 may bedivided into the same number of divisions as the shim-forming parts ofthe first to fourth die units 111, 112, 113, 114.

That is, in the first die unit 111 of FIG. 1, 15 shims 1 a dischargeddownwards from the first die unit 111 may be sorted and collected in 15divisions by the partition walls 131 a of FIG. 3. Further, in the fourthdie unit 114 of FIG. 1, 10 shims 1 a discharged downwards from thefourth die unit 114 may be sorted and collected in 10 divisions by thepartition walls 131 a of FIG. 3.

Further, in the second die unit 112 of FIG. 1, 10 shims 1 a dischargeddownwards from the second die unit 112 may be sorted and collected in 10divisions by the partition walls 132 a of FIG. 3.

Further, in the third die unit 113 of FIG. 1, 10 shims 1 a dischargeddownwards from the third die unit 113 may be sorted and collected in 15divisions by the partition walls 132 a of FIG. 3.

The shims 1 a sorted by the partition walls may be about 100 shims foreach division.
